FIG. 1 is an illustration of an example 100 associated with securing against network vulnerabilities, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 capable of communicating with a cyber security service provider (CSP) control infrastructure 104 for purposes of obtaining cyber security services. In some aspects, the one or more user devices 102 may communicate with the CSP control infrastructure 104 over a network 118. The CSP control infrastructure 104 may be owned and operated by a cyber security service provider and may include an application programming interface (API) 106, a user database 108, processing unit 110, and a security database 112. In some aspects, a user device 102 may include a communication application 114 and a processing unit 116. The communication application may include an application utilized by the user device 102 to communicate information and/or messages over the network 118. The communication application may include third-party applications such as, for example, a web browser application, an email application, a social network application, a messaging application, or the like. The API 106 may be capable of communicating with the user database 108 and with the processing unit 110. Additionally, the processing unit 110 may be capable of communicating with the security database 112, which may be capable of storing data associated with providing cyber security services.

The user device 102 may be a physical computing device capable of hosting the communication application 114 and of connecting to the network 118. The user device 102 may be, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 may include, for example, Internet-of-Things (IoT) devices such as MSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. The network 118 may be any digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network 118 may include one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The CSP control infrastructure 104 may include a combination of hardware and software components that enable provision of cyber security services to the user device 102. The CSP control infrastructure 104 may interface with (the communication application on) the user device 102 via the API 106, which may include one or more endpoints to a defined request-response message system. In some aspects, the API 106 may be configured to receive, via the network 118, a connection request from the user device 102 to establish a connection with the CSP control infrastructure 104 for purposes of obtaining the cyber security services. The connection request may include an authentication request to authenticate the user device 102. The API 106 may receive the authentication request and a request for the cyber security services in a single connection request. In some aspects, the API 106 may receive the authentication request and the request for the cyber security services in separate connection requests.

The API 106 may further be configured to handle the connection request(s) by mediating the authentication request. For instance, the API 106 may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API 106 may provide the received credentials to the user database 108 for verification.

The user database 108 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The cyber security service provider may add or delete such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API 106, the user database 108 and a processor (e.g., the processing unit 110 or another local or remote processor) may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the user database 108 and the processor may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the cyber security service provider may provide the security services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the cyber security service provider may decline to provide cyber security services to the user device 102.

When the user device 102 is authenticated, the user device 102 may initiate a connection with the CSP control infrastructure 104 for obtaining the cyber security services. The processing unit 110 included in the CSP control infrastructure 104 may be configured to determine the cyber security services to be provided to the user device 102. In some aspects, the processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the cyber security services. The processing unit 110 may utilize the API 106 to transmit information associated with the cyber security services to the user device 102.

One or more components (e.g., API 106, user database 108, processing unit 110, and/or security database 112, communication application 114, processing unit 116) included in the CSP control infrastructure 104 and/or included in the user device 102, as shown in FIG. 1 , may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 7 ). For instance, the one or more components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more components included in the CSP control infrastructure 104 may be separate and distinct from each other. Alternatively, in some aspects, the one or more of the components included in the CSP control infrastructure 104 may be combined with one or more of the other components. In some aspects, the one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the CSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the CSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the CSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory for execution by a processor. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, the one or more components may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

A user device may rely on a network (e.g., Internet) to communicate (e.g., transmit and/or receive) information and/or messages with other devices connected to the network. Such information and/or messages may include private information and/or sensitive data associated with the user device. Such private information and/or sensitive data may include, for example, financial information, medical information, business information, etc. In an example, the user device may communicate financial information by utilizing a web browser to conduct transactions with a device associated with a financial institution (e.g., a bank). In another example, the user device may communicate private information of a personal nature associated with, for example, a user of the user device by utilizing a messaging application and/or a social network application. In yet another example, the user device may communicate confidential information by utilizing an email application to conduct business with a device associated with a client or a business entity.

The communication of the information and/or messages over the network may be susceptible to a cybercrime perpetrated by a malicious party who may attempt to steal, alter, disable, expose, or destroy the information through unauthorized access to the communicating devices. A cybercrime may include, for example, a malware attack, a phishing attack, a ransomware attack, a virus attack, etc. The malware attack may be associated with use of malicious software (e.g., malware) designed to steal information and/or to damage the user device. The phishing attack may be associated with a malicious party communicating fraudulent messages (e.g., email) while masquerading as a reputable entity or an authorized entity, with the intent of stealing private information and/or sensitive data. The ransomware attack may include use of malware designed to render a system and/or information (e.g., a file, a document, etc.) on the user device unusable. The virus attack may include use of harmful software with an objective of affecting the user device (and other associated devices) with the intent of stealing data, interrupting operation, etc.

Because of increased prevalence in utilization of the network to communicate information and/or messages, it may be prudent to implement protective measures to secure the communicating devices and/or the communicated information/messages against cybercrimes. In some cases, the protective measures may include manual intervention. For instance, to avoid falling prey to a cybercrime, a user of the user device may manually inspect features associated with a network communication (e.g., a webpage, an email, a message, etc.) to ensure that the network communication is authentic. In an example, the user may manually inspect features such as images, text, layout, content, etc. included in the network communication to determine whether the network communication is associated with an authorized and/or authentic (e.g., non-malicious) entity. Specifically, the user may manually inspect whether an image and/or text displayed in association with the network communication is authentic, whether a layout of the image and/or text displayed in association with the network communication is authentic, whether content displayed in association with the network communication is authentic, etc.

Such manual inspection may be unreliable and error-prone. This is because manual inspection may be influenced by many factors such as age, state of mind, physical health, attitude, emotions, propensity for certain common mistakes, errors and cognitive biases, etc. Further, manual inspection may need to be performed at every instance of communication (e.g., for every webpage, every email, every message, etc.) over the network. Due to one or more of these factors, the user may fail to identify that the features of the network communication are not authentic and/or that the network communication is associated with an unauthorized and/or malicious party. As a result, the user may communicate the information and/or messages including the private information and/or sensitive data via the network communication. In this case, the private information and/or sensitive data may become compromised such that the unauthorized and/or malicious party may use the private information and/or sensitive data for nefarious purposes and/or to affect operation of the user device and/or to damage/destroy the user device. In an example, the operating system may run slower and/or associated circuitry may emit excessive heat and/or noise, thereby causing damage to the user device. The user device may expend various user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) in efforts to mitigate effects of the damage.

Various aspects of systems and techniques discussed in the present disclosure enable securing against network vulnerabilities. In some aspects, a CSP control infrastructure may provide a user device with an extension application to be associated with a communication application utilized by the user device to communicate information and/or messages over a network. The extension application may communicate with the CSP control infrastructure to receive authentic entity information including authentic feature information associated with authentic features (e.g., graphics, text, layout, content, etc.) included in authentic network communications (e.g., a webpage, an email, a message, etc.) associated with one or more authentic entities. The extension application may also receive updated authentic entity information from the CSP control infrastructure. Further, the extension application may receive the updated authentic entity information periodically. In some aspects, authentic entities may include an entity that is authorized to communicate with the user device and/or with whom the user device intends to communicate over the network. The received authentic entity information may also include a table of the authentic feature information (associated with a given authentic entity) being correlated with authentic network communication information (associated with the given authentic entity) (e.g., uniform resource locator (URL) link, domain information, etc.). When the user device utilizes current network communication information to communicate (e.g., transmit and/or receive) with a given entity over the network, the extension application may, in real time, analyze the authentic entity information and determine a portion of network communication information, from among the authentic network communication information included in the table, the portion of network communication information being associated with the given entity. Further, the extension application may utilize an associated processor (e.g., processor 116, processor 720) to compare, in real time, the current network communication information with the portion of network communication information. Based at least in part on a result of the comparison, the extension application may determine whether the current network communication information is authentic. In an example, when the current network communication information matches network communication information included in the portion of network communication information, the extension application may determine that the current network communication is authentic. Alternatively, when the current network communication information fails to match network communication information included in the portion of network communication information, the extension application may determine that the current network communication is not authentic (e.g., malicious). In this case, the extension application may cause the user device to issue a visual and/or audible notification indicating that the current network communication is not authentic. Based at least in part on the notification, the user device may suspend utilizing the current network communication to communicate with the given entity. In this way, private information and/or sensitive data associated with the user device may be prevented from becoming compromised. Further, the user device may be enabled to expend user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) for suitable tasks.

FIG. 2 is an illustration of an example flow 200 associated with securing against network vulnerabilities, according to various aspects of the present disclosure. The example flow 200 may include a user device in communication with a CSP control infrastructure 104. The user device may be similar to a user device 102 discussed above with respect to FIG. 1 . In some aspects, the user device may be associated with an account registered with the CSP control infrastructure 104. The user device may install an extension application associated with (e.g., provided by) the CSP control infrastructure 104. The user device may utilize the extension application to communicate with an application programming interface (API) and/or a processor (e.g., processing unit 110, processor 620) associated with the CSP control infrastructure 104. In some aspects, the user device and the CSP control infrastructure 104 may communicate with each other over a network (e.g., network 118). As discussed elsewhere herein, the CSP control infrastructure 104 may enable the user device to obtain cyber security services.

In some aspects, the user device may install communication applications to be utilized to communicate information and/or messages with other devices over the network. The communication applications may include third party applications such as, for example, email clients (e.g., Outlook application, Gmail application, etc.), web browsers (e.g., Firefox, Chrome, Internet Explorer, etc.), messaging clients (e.g., Slack, Facebook messenger, etc.), social media applications (e.g., Facebook, Instagram, etc.), or the like.

In some aspects, the user device may install the extension application, associated with (e.g., provided by) the CSP control infrastructure 104, as an extension to a communication application utilized by the user device to communicate information and/or messages with other devices over the network. Based at least in part on the extension application being installed as an extension to the communication application, the extension application may enable the user device to receive information to be processed by the communication application and/or by the CSP control infrastructure 104. The extension application may include respective graphical user interfaces to receive the information via local input interfaces (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the user devices. The information may be received via text input or via a selection from among a plurality of options (e.g., pull down menu, etc.). Further, the extension application may enable transmission of at least a portion of the information to the CSP control infrastructure 104. In some aspects, the extension application may activate and/or enable, at appropriate times, the graphical interface for receiving the information. For instance, the extension application may cause a screen (e.g., local screen) associated with the user device to display, for example, a pop-up message to request entry of the information. In some cases, as shown by reference numeral 230, the extension application may cause the screen associated with the user device to display, for example, a visual pop-up message to issue a notification. Further, the extension application may cause audio devices (e.g., speakers, headphones, etc.) associated with the user device to produce an audible message to issue the notification. In some aspects, the notification may include audible and/or visual messages. In some aspects, the extension application may utilize a processing unit (e.g., processing unit 116, processor 720) associated with the user device to perform such processes/operations associated with obtaining the cyber security services.

Although only one user device is shown in FIG. 2 , the present disclosure contemplates the system to include any number of user devices that perform the processes discussed herein in a similar and/or analogous manner.

In some aspects, the user device may receive cyber security services from the CSP control infrastructure 104. When the user device is authenticated, the user device may initiate a connection with the CSP control infrastructure 104 to obtain the cyber security services. While obtaining the cyber security services, as shown by reference numeral 210, the CSP control infrastructure 104 may transmit, and the user device may receive, authentic entity information. In some aspects, the authentic entity information may include authentic feature information and an authentic entity table.

In some aspects, the authentic feature information may indicate a known characteristic of a known authentic feature included in a known authentic network communication associated with a known authentic entity, with which the user device intends to communicate over a network. In some aspects, the authentic feature information may be associated with authentic features such as, for example, graphics (e.g., illustrations, diagrams, photos, logos, etc.), text, layout, content, etc. included in authentic network communications such as, for example, websites, emails, messages, etc. associated with one or more known authentic entities. The CSP control infrastructure 104 may determine, for each authentic entity, such authentic feature information based at least in part on analyzing the authentic network communications and correlating the authentic features with the authentic network communication information (e.g., URLs, domain names, etc.) associated with the authentic network communications.

In an example, the CSP control infrastructure 104 may systematically analyze one or more authentic websites known to be associated with an authentic entity to determine characteristics regarding the authentic features included in the one or more authentic websites. For instance, the CSP control infrastructure 104 may determine the characteristics regarding appearance of one or more graphics on an authentic webpage associated with an authentic website. Such characteristics may include a size associated with the one or more graphics, a color associated with the one or more graphics, a position associated with the one or more graphics, etc., or a combination thereof, on the authentic webpage. Also, the CSP control infrastructure 104 may determine characteristics regarding text appearing on the authentic webpage. Such characteristics may include a font size associated with the text, a font color associated with the text, a positioning of the text, etc., or a combination thereof, on the authentic webpage. Further, the CSP control infrastructure 104 may determine characteristics regarding a layout of information on the authentic webpage. Such characteristics may include a relationship between a position of the one or more graphics with a position of the text on the authentic webpage. Furthermore, the CSP control infrastructure 104 may determine characteristics regarding content included in the authentic webpage. Such characteristics may include a set of keywords associated with the content included in the authentic webpage.

In some aspects, the authentic websites may be associated with all websites published on the World Wide Web, especially those authentic websites that may be more susceptible to cybercrimes. In an example, the CSP control infrastructure 104 may specifically analyze authentic websites associated with elevated security concerns such as websites associated with, for example, financial institutions, business entities, medical institutions, educational institutions, etc. In another example, the CSP control infrastructure 104 may analyze authentic websites that observe a threshold amount of data traffic such as websites associated with, for example, research websites (e.g., Google), social media websites (e.g., Facebook), etc.

Similarly, the CSP control infrastructure 104 may determine characteristics regarding appearance of one or more graphics on one or more authentic emails and/or messages (e.g., email/messages) associated with (e.g., received from) the authentic entity. Such characteristics may include a size associated with the one or more graphics, a color associated with the one or more graphics, a position associated with the one or more graphics, etc., or a combination thereof, on an authentic email/message. Also, the CSP control infrastructure 104 may determine characteristics regarding text appearing on the authentic email/message. Such characteristics may include a font size associated with the text, a font color associated with the text, a positioning of the text, etc., or a combination thereof, on the authentic email/message. Further, the CSP control infrastructure 104 may determine characteristics regarding a layout of information on the authentic email/message. Such characteristics may include a relationship between a position of the one or more graphics with a position of the text on the authentic email/message. Furthermore, the CSP control infrastructure 104 may determine characteristics regarding content included in the authentic email/message. Such characteristics may include a set of keywords associated with, for example, a domain name (e.g., @entity.com, etc.) associated with the authentic entity.

In some aspects, the authentic email/messages may be associated with all active domain names, especially those active domain names that may be more susceptible to cybercrimes. The CSP control infrastructure 104 may specifically analyze authentic email/messages associated with elevated security concerns such as email/messages associated with, for example, financial institutions, business entities, medical institutions, educational institutions, etc. The CSP control infrastructure 104 may analyze authentic email/messages that observe a threshold amount of data traffic such as email/messages associated with, for example, popular websites (e.g., Gmail, Yahoo, etc.), social media websites, etc.

In some aspects, as shown in example 300 of FIG. 3 , the processing unit 110 included in the CSP control infrastructure 104 may include and/or utilize a self-learning machine learning model (ML model) 310 in connection with analyzing the authentic network communications (e.g., a website, an email, a message, etc.) and correlating the authentic features with the authentic network communication information (e.g., a URL, a domain name, etc.). In some aspects, the ML model 310 may include a supervised learning model. In some aspects, the ML model 310 may include an unsupervised learning model. The processing unit 110 may utilize the ML model 310 to automatically and with improved accuracy analyze the authentic network communications and correlate the authentic features with the authentic network communication information

As shown by reference numeral 320, the ML model 310 may obtain training data including metadata and/or previous metadata associated with information received during at least one previous instance of analyzing the authentic network communications and correlating the authentic features with the authentic network communication information and/or update data associated with an output provided by the ML model 310 during at least one previous instance of analyzing the authentic network communications and correlating the authentic features with the authentic network communication information. In some aspects, the processing unit 110 may store the above training data in, and the ML model 310 may obtain the above training data from, for example, one or more memories described elsewhere herein (e.g., security database 112, memory 730). In some aspects, the previous metadata may include historical metadata associated with the at least one previous instance of analyzing the authentic network communications and correlating the authentic features with the authentic network communication information. In some aspects, the update data may include historical output data associated with at least one previous instance of analyzing the authentic network communications and correlating the authentic features with the authentic network communication information. In some aspects, the ML model 310 may obtain input training data that is input via an interface associated with the CSP control infrastructure 104.

As shown by reference number 330, the ML model 310 may process the training data using a machine learning algorithm (ML algorithm). In some aspects, the ML model 310 may utilize the ML algorithm to evaluate the training data to learn trends and patterns associated with analyzing the authentic network communications and correlating the authentic features with the authentic network communication information. In some aspects, the ML algorithm may evaluate and take into account feedback information (e.g., success rate) associated with previously analyzing authentic network communications and correlating authentic features with the authentic network communication information. The ML algorithm may provide output data to the processing unit 110 based at least in part on the evaluated training data and the learned trends and patterns. In some aspects, the output data may indicate a value associated with the likelihood that the authentic network communications were analyzed successfully and/or that the authentic features were successfully correlated with the authentic network communication information, thereby assisting the processing unit 110 in more accurately automating the analyzing of the authentic network communications and correlating of the authentic features with the authentic network communication information.

As shown by reference number 340, at an end of an instance of automating the analyzing of the authentic network communications and correlating of the authentic features with the authentic network communication information, the ML model 310 may receive update data including at least the training data and/or the output data. In some aspects, the update data may be included in the previous metadata stored in the one or more memories (e.g., security database 112, memory 730) to be used as training data for future iterations of automating analyzing of the authentic network communications and correlating of the authentic features with the authentic network communication information. In some aspects, the ML model 310 may evaluate the update data to learn various aspects such as accuracy, consistency, reliability, efficiency, and/or the like of the output data in enabling the processing unit 110 to more accurately analyze the authentic network communications and/or to correlate of the authentic features with the authentic network communication information. In this way, the processing unit 110 may utilize the ML model 310 to apply a rigorous and automated process to analyze the authentic network communications and/or to correlate the authentic features with the authentic network communication information. In some aspects, the ML model 310 may enable the processing unit 110 to more accurately analyze the authentic network communications and/or to correlate the authentic features with the authentic network communication information.

In some aspects, the CSP control infrastructure 104 may also determine, for one or more authentic entities, an authentic entity table of authentic feature information (associated with a given authentic entity) correlated with authentic network communication information (associated with the given authentic entity). In an example, the CSP control infrastructure 104 may determine correlations of, for example, authentic graphics, text, layout, content, etc. associated with the given authentic entity with, for example, authentic website URLs, domain names, etc. associated with the given authentic entity. Further, the CSP control infrastructure 104 may store the correlations in the authentic entity table.

As shown by reference numeral 220, based at least in part on receiving the authentic entity information, including the authentic feature information and the authentic entity table, the extension application may utilize a local and/or remote processor (e.g., processor 116, processor 720) associated with the user device to secure the user device (and other associated devices) against network vulnerabilities. In an example, the extension application may utilize the local and/or remote processor to determine whether a given (e.g., currently used) network communication is authentic. In some aspects, the extension application may store the received authentic entity information in a local and/or remote memory (e.g., memory 730) associated with the user device.

When the user device utilizes the communication application to communicate with an entity over the network, the user device may utilize current network communication information (e.g., URL link, domain information, etc.) associated with a current network communication (e.g., website, email, message, etc.). The user device may not know whether the entity is the authentic entity, whether the current network communication information is authentic, and/or whether the current network communication is authentic. In this case, the extension application may monitor current features (e.g., graphics, text, layout, content, etc.) included in and/or associated with the current network communication. Further, the extension application may determine, for each current network communication, current feature information based at least in part on analyzing the current features observed with respect to the current network communication. In some aspects, the current feature information may indicate an observed characteristic of a current feature included in the current network communication associated with the current entity with which the user device is communicating or with which the user device is to communicate over the network. In some aspects, a user of the user device may observe such current features associated with the current network communication on a screen (e.g., output component 760) associated with the user device.

In an example, when the user device utilizes a web browser application to communicate via a current website, the extension application may systematically analyze a current webpage associated with the current website to determine current feature information regarding the current features observed with respect to a current webpage. For instance, the extension application may determine current feature information regarding appearance of one or more graphics on the current webpage. Such information may include a size associated with the one or more graphics, a color associated with the one or more graphics, a position associated with the one or more graphics, etc., or a combination thereof, on the current webpage. Also, the extension application may determine current feature information regarding text appearing on the current webpage. Such information may include a font size associated with the text, a font color associated with the text, a positioning of the text, etc., or a combination thereof, on the current webpage. Further, the extension application may determine current feature information regarding a layout of information on the current webpage. Such information may include a relationship between a position of the one or more graphics with a position of the text on the current webpage. Furthermore, the extension application may determine current feature information regarding content included in the current webpage. Such information may include a set of keywords associated with the content included in the current webpage.

Similarly, when the user device utilizes an email application and/or a messaging application, the extension application may determine current feature information regarding appearance of one or more graphics observed with respect to a current email/message. Such information may include a size associated with the one or more graphics, a color associated with the one or more graphics, a position associated with the one or more graphics, etc., or a combination thereof, on the current email/message. Also, the extension application may determine current feature information regarding text appearing on the current email/message. Such information may include a font size associated with the text, a font color associated with the text, a positioning of the text, etc., or a combination thereof, on the current email/message. Further, the extension application may determine current feature information regarding a layout of information in the current email/message. Such information may include a relationship between a position of the one or more graphics with a position of the text in the current email. Furthermore, the extension application may determine current feature information regarding content included in the current email/message. Such information may include a set of keywords associated with, for example, a domain name (e.g., @entity.com, etc.).

Based at least in part on determining the current feature information, the extension application may compare the determined current feature information with the authentic feature information stored in the memory (e.g., memory 730) associated with the user device. In some aspects, the extension application may compare the current feature information with the authentic feature information to determine whether the current network communication (e.g., a website, an email, a message, etc.) is authentic. For instance, when the current feature information fails to match at least a portion of the authentic feature information (e.g., is substantially different with respect to the authentic feature information), the extension application may determine that the current features (e.g., graphics, text, layout, content, etc.) are not authentic. Further, based at least in part on the current feature information failing to match at least a portion of the authentic feature information, the extension application may determine that the current features are not associated with an authentic entity. In this case, the extension application may determine that the current network communication being utilized by the user device to communicate is not authentic. As a result, the extension application may cause the processor associated with the user device to suspend utilization of the current network communication and/or to provide a visual and/or audible notification indicating that the current network communication is not authentic. Such a notification may indicate that the user device is susceptible to a cybercrime based at least in part on utilizing the current network communication. In some aspects, suspending utilization of the current network communication may include suspending communication of information in association with the current network communication.

Alternatively, when the current feature information matches (e.g., is substantially similar to) at least a portion of the authentic feature information, the extension application may determine that the current features (e.g., graphics, text, layout, content, etc.) is authentic and associated with the authentic entity with which the portion of the authentic feature information is correlated in the authentic entity table. Also, based at least in part on the current featured information matching at least a portion of the authentic feature information, the extension application may determine that the current feature information is authentic. Further, the extension application may compare the current network communication information (e.g., URL link, domain information, etc.) with the authentic network communication information associated with the authentic entity included in the authentic entity table. When the current network communication information matches at least a portion of the authentic network communication information, the extension application may determine that the current network communication information is authentic. In some aspects, when the current network communication information entirely matches the authentic network communication information, the extension application may determine that the current network communication information is authentic. Based at least in part on the current network communication information matching at least a portion of the authentic network communication information or based at least in part on the current network communication information entirely matching the authentic network communication information, the extension application may determine that the current network communication information is associated with the authentic entity with which the portion of the authentic feature information is correlated in the authentic entity table. In this case, the extension application may determine that the current network communication being utilized by the user device to communicate is authentic. As a result, the extension application may enable the processor associated with the user device to continue utilization of the current network communication.

In this way, private information and/or sensitive data associated with the user device may be prevented from becoming compromised. Further, by conducing the more process-intensive task of training the machine learning model at the CSP control infrastructure to more accurately analyze the authentic network communications and/or to correlate the authentic features with the authentic network communication information and by transmitting the authentic entity information to the user device, the user device may be enabled to conserve user device resources and efficiently utilize such user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) to perform less process-intensive tasks associated with securing the user device against network vulnerabilities.

In some aspects, the process 500 may be performed by a memory and/or a processor/controller (e.g., processing unit 110, processor 720) associated with an infrastructure device (e.g., CSP control infrastructure 104). As shown by reference numeral 510, process 500 may include determining, by an infrastructure device in communication with a user device, authentic feature information that indicates a characteristic associated with an authentic feature included in an authentic communication associated with an authentic entity, with which the user device intends to communicate over a network. For instance, the infrastructure device may utilize the associated memory and/or processor to determine, while in communication with a user device, authentic feature information that indicates a characteristic associated with an authentic feature included in an authentic communication associated with an authentic entity, with which the user device intends to communicate over a network, as discussed elsewhere herein.
